Office supplies supplier needed

Ideally I would like to have one source for all my office supplies. I need basically everything a retail store would sell. No big single items like printers or registers etc but pens, paper, punches, tape etc etc.

My main concern is cheap... not drop shipping either.

I'm worried the US is going to be too expensive and I would like to import it to Chile. If I have to use multiple suppliers I can but if someone has most of everything that would be great.

There are a couple of drop shippers here but they offer wholesale options too. Should you use any of these suppliers, please let us know how you got on by adding a short review on the supplier profile page. Thanks.
